Solvent extractor: 30T Cotton seed cake solvent extractor. 1) Fixed material layer large spray Leaching of A Fixed Large Sprayer In Leaching Process

The main advantages of fixed feed-storey spray leaching process is leaching material lattice thickness of 2-2.5 meters.

Material layer is relatively fixed, the concentration gradient of different mixed oil and fresh solvent through large spray material layer, in the upper surface of the liquid form of 30-50 mm, so that the whole grid feed materials are in contact with the solvent extraction; at the same time, mixed oil circulating spray to take "Ever since the grid," to collect the overflow grid, thus ensuring maximum fat blank sheet leach out, so that the residual oil meal ≤1%.

2) DT wet meal Process

    For the preparation of high quality, good color, soybean meal, choose the right wet treatment process is very important meal

A. DT steaming hot off process is to take direct steam stripping off the solvent, indirect steam assisted desolventizing. Ensure complete passivation meal urease, meal residue dissolved less than 500ppm.

3) Cold water circulation solvent recycling technology:

The Cold-Water Solvent Recycling Process

Cooling tower is designed to recycle packing structure, the use of water jet pump will produce exhaust systems lead onto the absorber bottom, after stratification overflow into the sub-tank solvent recovery, while the role of the vacuum jet pump so that the whole system to produce slightly negative pressure effectively put an end to the phenomenon of leaking under positive pressure solvent. Special packing absorber structure of the vapor-liquid two-phase solution area have a greater access, high absorption efficiency, avoiding the use of refrigeration recycling and high maintenance costs and poor absorption of the shortcomings of small-tonnage oil extraction plant ideal exhaust recovery devices.

    Selection is based on extraction plant equipment safe, reliable, energy saving, less failure, easy maintenance, long life

Principle, in the selection by the selection of new equipment with advanced energy-saving technology to achieve the best results. Specific performance in the following areas:

1) The continuous improvement of the fixed grid rotocel solvent Extractor

Appropriate to increase the height of the extractor feed grid will help improve circulation leaching effect. Increasing the height of the collection grid, and eliminating the need for mixing oil temporary storage tank. In order to prevent the oil from flowing back into the rich blanking grid, increasing the lateral grid.

2) DT toaster and desolventizer

After DT toaster and desolventizer improved, its upper structure is big hat head, material falling from the dispensing tray, one, two pre-off, three for the steam off, after four off, five dry.

The structure advantages: instead of four further desolventizing stage, can not properly heated or heated depending on the circumstances, can effectively avoid the high boiling solvent is evaporated without a net, resulting in a high solvent loss shortcomings; five drying, heating may be appropriate under the circumstances or directly with the cold, it proved 1050C direct cooling with cold air hot meal that is dry and has a good cooling effect, energy consumption is greatly reduced. In short, the improved steam offline DTD has to save power, save energy, low solvent loss, meal at the end of a small, significant advantage dried and cooled and used.

3) Condensor

It uses heat exchange theory, using cold water to condensate the evapated solvent gas and steam.

4) Stripper

    The new stripper, a unique spherical baffles make oil flow uniformity and dispersion of the vapor and liquid contacting uniform, thorough, removing the solvent and strong ability level, and to reduce the production of vapor due to fluctuations in crude oil caused by residual solvent the phenomenon of low high when crude oil in total volatiles greatly reduced, to ensure the safety of leaching refining of crude oil.

The Cotton seed cake solvent extractor 30Ton is popular for small users or who just starts the business of solvent extractor.
